United States Patent 3,162,356 PHONOGRAPH RECURD ENVELQPE Louis Triolo, 26 llulwer Place, Brooklyn, NY. Filed Get. 28, 1963, Ser. No. 319,121) 2 Claims, (Cl. 229-68) This invention relates to phonograph record housings and relates more particularly to a record enclosure which will have a uniform thickness over its entire area when enclosing a record, thus allowing the stacking of records without any unevenness in the stack or bending of the record.

The better quality of records which have a relatively high price usually are believed by the customers to merit an attractive enclosure for the simple paper envelope within which the record is initially placed. It has been a practice to form a cavity in the housing of the approxi mate depth or thickness of the record. This is done by forming what is in effect a box with shallow side walls rather than a simple flat envelope. The housing of the present invention is square and is formed from a cardboard blank of double the size of the housing to provide upper and lower walls which are joined by a shallow end wall opposite to the open side through which the paper envelope enclosing the record is inserted.

The two remaining edges have side walls formed integrally with the bottom wall and these side walls have inturned glue flaps which are adhesively joined to the opposed margins of the top wall. These glue flaps extending the full length of the sides of the envelope cause an objectionable variation in thickness of the housing since in these two areas there are three thicknesses of cardboard while the remaining area, amounting to about 95%, has two thicknesses of cardboard. The only place, however, where these three layers of cardboard cause any trouble is in the two arcuate areas where the opposite edges of the circular record underlie these glue flaps.

To remedy this difiiculty, in the present invention the edges of the top wall are cut away in the areas overlying the opposed edges of the record. This does not, however, cause a weakening of the housing since the upper or lower wall of the folded cardboard blank is covered with a Wrapper having margins which extend over the edges of the other wall and the latter, including these margins, are covered with an adhesive label.

Also, to avoid the glue flaps causing an obstruction to the entering envelope containing the record the flaps are also cut away a short distance at the open side.

in the drawing:

FIG. 1 is a perspective view of the finished record envelope of the present invention without, however, the wrapper and label;

FIG. 2 is a broken section taken on lines 22. of FIG. 1;

FIG. 3 is a broken section taken on lines 33 of FIG. 1;

FIG. 4 is a broken section taken on lines 4-4 of FIG. 1;

FIG. 5 is a section similar to FIG. 4, but shows the relation of the parts when the envelopes are stacked one upon the other;

FIG. 6 is a broken elevation of the finished record envelope with the record in place therein; and

FIG. 7 is a broken plan view of the blank used in forming the envelope.

The rectangular housing of the present invention is made from a rectangular cardboard blank having square upper and lower wall sections 1%? and 11 which are con nected by an end wall 12 defined by two creased or otherwise weakened lines 14 which are spaced apart a distance equal to the thickness of a phonograph record. This end wall is of a depth equal to the depth of the record.

3,162,356 Patented Dec. 22, 1964 The bottom wall has lateral extensions along opposed sides adjacent end wall 12, each provided with crease lines 15 and 16 forming side walls 17 of the same height as end wall 12, and glue flaps 18 with a free edge 19. The margins of edges 20 of top wall 10 have cut-out sections 21 and 22, each being of a width at least as wide as glue flap 13.

Cut-out section 21 is disposed centrally of edge 20 of the top wall and is of a length from A to /3 the length of the edge. The short cut-out section 22 at the front or open side of the housing need be only one inch or thereabouts in length. The housing may be fabricated by hand or by automatic machinery and glue strips are applied to the upper edges of glue flaps and the upper wall 10 pressed downwardly against the flaps, preferably while the flaps are supported by a mandrel. The envelope may also be fabricated by the machine disclosed in my co-pending application, Serial No. 270,435, filed April 3, 1963, which has means for adhering the upper wall to the glue flaps without a mandrel and without crushing the side walls.

The housing may now be covered with an adhesively applied cover sheet which may comprise a wrapper and a label. The wrapper is shown at 26 as covering upper wall 10 and has a portion 28 extending over side wall 17 and a margin 29 extending over the edge of bottom wall 11. The label 30 extends over the entire lower face of the housing including the margin 29 as shown at 31.

It will be noted in FIG. 7 that the end wall 12 is of approximately the same depth as side walls 17. Since the edges 20 of top wall 10, except in the areas of the cut-away sections 21 and 22, are adhered to the tops of the glue flaps 18, the depth of the record receiving cavity along edges 26 is greater than in the areas of the cut-out sections by an amount equal to the thickness of the cardboard.

This is clearly shown in FIG. 3 and the depth of the cavity C is greater than the thickness of the record R. The same is true of the condition in the area of cut-out section 21 before any compression has been exerted on the housing from above. This is true since the margins of the upper wall 19 in the area of the cut-away sections 21 are on the same level as the balance or" this upper edge 20. This is shown in FIG. 4. When such pressure is applied from above, this edge 21 moves downwardly to the plane of the glue flap 18 and the cavity C now has the same depth as the thickness of the record. This condition is shown in FIG. 5. Before this compressive action has occurred the side walls 17 are generally straight but when the lower wall 11 and the flap 18 are brought closer together the side wall is bowed outwardly and is, therefore, slightly curved as shown at 1'7 in FIG. 5. In the event that the housing did not have the ouside paper cover sheet 26 and label 30 the downward movement of edge 21 to the plane or" glue flap 18, shown in FIG. 5, would occur every time compressive action were applied to the housing, as when several records are stacked. When the adhesive cover sheet 26 is applied, enough pressure is also applied to bring about the condition of FIG. 5 which shows edges 21 and 1% lying on the same plane and in substantial abutting relation.

The same condition exists at the mouth of the recordreceiving opening shown in FIG. 6. In order to indicate the several layers, the thickness of the inturned margin 29 of the cover sheet and the overlaying margin 31 of the label is exaggerated. Actually the thickness of these paper wrappers is negligible.

Thus, when the cover sheet 26 is afiixed the glue flap 18 is on the same plane as the edge 21 of the top wall and the adhesive bond causes this condition to continue. The essential structural feature here is that the forward edge 19' of the glue flap 18 does not act as an abutment to restrain free inward travel of the record envelope (not shown) with the record therein into the housing.

While there have been described herein what are at present considered preferred embodiments of the invention, it will be obvious to those skilled in the art that many modifications and changes may be made therein without departing from the essence'of the invention. It is therefore to be understood that the exemplary embodiments are illustrative and not restrictive of the invention, the scope of which is defined in the appended claims, and that all modifications that come within the meaning and range of equivalency of the claims are intended to be included therein.
